50 Bmg Blow up....

Why in the world are you guys wasting time on this troll?

Dammit!
You are absolutely correct. I've got a button to fix this.......
But later.....I'm not bored yet. He's dumb as a bag of hammers, but he has a little talent.

Not really... it could have been ok but honestly it's still sad.

Shit if you want to shoot a low end 50, seems you found the path that suits you.
I have no interest in owning a 50, but if I did, I would want to feel confident it is the best available.
I like my face.

Another baseless comment with nothing to add...and you don't even own a 50. Nice. Over half the posts in this thread have no basis to the issue at hand, yet here we are, jumping on the bandwagon to nowhere. Talk about a clown act...

I don't own a tractor.
But I have operated one for many hundreds of hours.

Are you really this stupid?

 

[Srgt. Hulka]

I understand real engineering. I also understand engineering and building concepts that are out of the box thinking. Its what drives innovation and design. How many new ideas have there been presented in the gun world in the last few years...that have taken off? Lets eliminate the same old ideas and just the new ones. The Laugo arms pistol is one...

edit to add...if there had been other Serbu rifles that had catastrophic failures, as this rifle was built specifically for SLAP rounds, then I would be agreeing with everything you all have posted. One failure does not make a pattern. Nor does it suggest the rifle was the issue.

I’ve said it once, and I’ll say it again; this is all I see when I look at that gun. A pipe with a pipe cap on the end. All it needs is a fuse sticking out the back.

 

[CMP70306]

You know you have hit the target when all the comments that come back at you are personal in nature and nothing to do with the matter at hand.

I have nothing in this fight other than the experience of dealing with the guy and how committed the guy is to this community and the 2nd Amendment. Contrary to your beliefs, the guy does a great job at designing awesome guns...and the fact he is backlogged for 2 years proves that point.

You guys who poo poo him with no merit, lots of speculation and he said, she said comments having nothing on him.

Only a putz would buy a Hi-point, you making my point.

I am surprised so many of you have jumped on the innuendo bandwagon...when so many outside of this forum have reached different conclusions. It must be nice having a circle jerk with so many like minded members, stroking each others ego's, at the detriment of our community and those who make it better by the designs they bring and the support they give.

Having an 18 month wait (per his site) doesn’t mean much when you are offering something well below market value and you only make a few hundred a year. Also the only thing special about them is that they are the cheapest .50 BMG you can buy, that’s it. They are the Hi-Point of the .50 BMG world yet you laugh at Hi-Points and miss the irony.

I never said you were wrong. From the first pages of this thread you had already made up your mind on Serbu...I can read it in your posts. So much for letting the facts come out before making a call...and as they do come out with the facts, this failure would have happened to basically any rifle...the only difference being, how much damage would it have caused in other makes.

The amount of speculation in this thread from the get go still continues...even though the information surrounding this failure is coming out and clearly laying fault with the round...yet you have a hard one for making Serbu look like the bad guy.

The post with the pistol that shot the firing pin group into the guys eye...I guess you are going to go all ape shit on that manufacturer too? Your disdain for Serbu seems to be more than meets the eye.

Well if we see here Orkan loaded up a DTA SRS in 338 Lapua with pistol powder, jammed the bullet into the lands generating well in excess of 120k psi based on some rough QuickLoad numbers and other than some galled bolt lugs the rifle was fine.



Ted at American Rifle company tested his action by shooting a factory 300 WSM round in a barrel with a cleaning rod placed in it, the action was functionally damaged but intact so the shooter wouldn’t even be injured if they had safety glasses as the majority of the gas and debris was safely diverted away from the shooter. Even with the massive pressure generated by a completely obstructed bore the bolt would not fly back into the shooter.




After watching Serbu’s videos by the looks of it the case failed and the action had nowhere to vent the extra gas so the force was transferred to the cap which has approximately 3 to 4 times the surface area of the case head depending upon the diameter of the cap. Since the forces generated by the pressure are relative to the area it is acting on, by increasing the area from just the case head to the full cap you drastically increase the force on the cap to the point it exceeded the threads ability to contain it.

Look at the cap in his video, if the round itself was so high pressured that it alone generated enough force to break the cap then there should be some brass smeared onto the cap from the force of the case head being smashed into it at a supposed 160k psi. As you can see below there is not.

His video saying you can’t have a case head separation without excessive headspace or the action failing and moving backwards is bullshit. If the brass is weak in the web it’s going to split and the gas is going to find the path of least resistance.

Had the design incorporated some way of diverting the gas flow the rifle might have been saved from catastrophic, life threatening failure.

 

[seanh]

I'm just spit balling here, never heard the final cause of failure... My guess is the cap wasn't fully tightened And when the hot gas is combined with pressure flow over the threads it caused a plasticization (sp?) at the threads causing sheering..

It’s designed so it can’t close if front of the ears (the ones that got lodged in scotts throat) if the cap isn’t completely threaded on

The final cause: It’s a pile of shit and acted accordingly

This rifle was designed with the cap to close in front of both ears which were part of the lower assembly. If the cap is not screwed on tight enough, the ears will prevent it from fully locking into place.

I can't imagine the amount of pressure needed...not only to shear all of the threads off completely, but also remove both of the ears which were integral to keeping the cap in place...one can only imagine the detonation and speed at which it occurred for this to happen.

I suspect a smaller detonation might not have sheared off both ears, but instead might have deflected it upward, since there was no restriction to movement above the ears.

You mean shear off 3 threads, because that’s all the engagement there is.

There have been a couple good posts in the last 24 hours telling you why this piece of shit failed that you have chose to ignore

 

[...]

As ive mentioned before....but I'll mention again for the autistic "members" in this thread.....making this design safer is actually really simple.

1) design a lower that fully encapsulates the screw cap

2) make the front take down pin a shear pin


In the event of a failure, it will "blow forward" instead of launching debris straight back at the shooter.


Literally Design 101

Thanks!

I love Ted. He def seems to walk to the beat of his own drum a bit, but in that vid is an example of how a real engineer would address safety in a device like an action.

I have his rings but not one of his actions. But I wouldn’t hesitate to use any of his products.

Serbu……nah.

 

[THEIS]

Hi,

GEEZUS Christ this thread is still going, lolol!!!

All this talk from Serbu themselves of subsequently this, subsequently that, looking into this, assuming that, etc etc.....
That is NOT how engineering works.

Here are the bottom line FACTS; like it or not....

1. Within 5 minutes of Serbu finding out about the catastrophic failure he should have been able to show his independent and insurance company approved Dynamic FAE and Motion analysis that shows EXACTLY what those pressures would have had to be in order to replicate the catastrophic failure. As this should/would have been done, certified and signed off on BEFORE the public release of the very first rifle.

2. Within 5 minutes of Serbu finding out about the catastrophic failure he should have been able to show his alloy certifications...He still hasn't shown them and how long has the event been?

3. Within 5 minutes of Serbu finding out about the catastrophic failure he should have been able to show his heat treatment certifications...He still hasn't shown them and how long has the event been?

4. Within 5 minutes of Serbu finding out about the catastrophic failure he should have been able to show the National welding certification for everyone in his shop that touches the welding machine (And just in case anyone is wondering why that....soon as that welding arc touches any metal the alloy composition changes)...He still hasn't shown them and how long has the event been?

5. The FACT Serbu still cannot show the Dynamic FAE and Motion analysis highlights just how far behind this catastrophic failure events' power curve he really is. That is evident in his numerous post event videos where he attempts to point the finger at everything but his design.
Now we have his shill actually blaming it on the Youtube video creators looking for bigger "wow" factors, lololol.......


So since the Serbu crowd likes to keep guessing....type your guesses to the following:

Guess what pressure needs to be for this event IF the alloy was improperly heat treated.....
Guess what pressure needs to be for this event IF the alloy composition was "shortcutted"....
Guess what pressure needs to be for this event IF Serbu internal quality processes did not monitor the heat from the stoned welding guy....

*Hint....it would not need "over pressured" ammunition to cause the event as it occurred.


Edited To Add: In response to the backlog he has, lolol.....
Well... he is selling the YEETS (YO, Evacuate Everyone To Safety) cannon of the rifle world...

Theis

Regardless the state of the cap doesn’t reflect how he says the event happened. Based on the outcome any case head separation in that rifle results in the firearm becoming a pressure vessel and the failure point is aimed directly back at the shooter.

If you don’t understand why 3-4 threads hand tight is different that full thread engagement and torqued to spec than I don’t know what to tell you. 3-4 threads hand tight does not hold 160ksi.

If you do not understand why that serbu rifle is a giant pile of shit and Mark serbu and his shop are absolute hacks After reading the replies here you are beyond help. Why don’t you buy one, load up a couple ladder tests up to 80ksi and see how well it fairs. Just make sure you cancel all your insurance policies before hand so no one else is stuck with the bill for being stupid besides yourself.

I own two of his rifles...both 50A versions.

Some engineers would disagree with your assessment of a four thread hold...which is considerably different than a three thread hold. There are a few YT videos which explain the concept very well in layman terms. Might suggest you pop over and watch them.

I have read the entire thread...amazing what passes for fact over speculation...seems some here don't like to differentiate between the two.

There is always an improvement that can be made to a rifle. Even some of the most expensive, well designed rifles, have limitations to how well they will fail under a faulty load.

Hopefully, we have all learned the importance of treating any gun with the operational care they command and not do stupid things with them, even after there are signs of something going wrong.

If I triggered any of you with my opening comment, my apologies. That was not really my intent...but it served its purpose.

Not everything is at it seems, even when you try to brow beat everyone into seeing it your way. There are enough open ended questions regarding this failure we should all be learning from...and I am sure Mark Serbu is and has been, ever since he learned of this failure to one of his rifles. Its unfortunate, regardless of what he says or does, it will never be good enough for some of you. To that I add...I hope none of you are ever in a position to have to defend yourselves from an overzealous group of gun owners who just don't like you.

Peace Brothers...

I read enough of this thread to know I was going to be in the minority. I have seen and heard many other explanations to what the cause and effect of a deleterious round would do to ANY rifle.

How much pressure are you going to design into a gun to safely blow up?

Now you're asking the right questions. The problem is that Serbu HAD NO IDEA what the answer to this question until AFTER it exploded and he hired a company to test it...

What would you have done to make this rifle safer from a catastrophic failure?

Vent ports are a thing, materials selection, etc. All kinds of different methods that you can use to direct failure. If none of them work properly, usually the course of action is to go back to the drawing board and find a new solution, not release it anyway.

Appreciate the response and not the petulance exhibited from others for the most part.

I will say the amount of pressure required to cause a failure seemed low to me from his original comments he made. And you are correct...once he had the other party do a pressure analysis on what the threads and cap could sustain, the numbers seemed more in line with what you would expect from a large caliber rifle. As others had mentioned, smaller caliber rifles experienced the kinds of pressure mark initially suggested were in play.

I have always appreciated the contributions NASCAR has made to cars in general. I think there are always things to be learned and better understood when you have an open mind in how you look at things. I am not a car designer, but I do appreciate the safety and understand the concept behind crunch zones...something that was learned through nasty accidents in race cars. Amazing how one car survive a head one collision at over 150mph...and technology/engineering is behind it.

Let's be honest...no one is "shooting the hell" out of these things....

If you cannot afford an actual .50, you can't afford the $5-10/round to feed it.

Ide hazard a guess 90% of the people who bought one of these have shot it less than 10 times before they realized they can't afford it.....and now they just sit in the back of the safe.

No one is putting hundreds of rounds through these things....which is probably a good thing.

It could be argued then, and you are making my point I had in back of my mind, that this cat ass trophy was made possible by someone who actually shot the hell out of it.
Yeah, the ammo was the problem. The literal volume of ammo fired. Nothing more.
It reached the fatigue point, and failed. Period.

Saying the ammo was the problem is pure theory.

You're still implying Serbu's rifle is innovation or applying new technology... It's not. It's an attempt to build a cheap as possible 50 BMG by cutting as many corners as he can get away with. The "action" is a glorified pipe shotgun with a safety. There was little to no engineering or testing done for this rifle as evidenced by the fact that Mark had no idea what the rifle could withstand until one blew up. The firearms industry as a whole has moved far beyond this type of junk. I'm not even trying to rag on Mark as a person or even diminish design capabilities he may have, just pointing out that this rifle was a mistake on pretty much every level.

Ide hazard a guess 90% of the people who bought one of these have shot it less than 10 times before they realized they can't afford it.....and now they just sit in the back of the safe.

No one is putting hundreds of rounds through these things....which is probably a good thing.

If you want to be real honest, many are shooting the heck out of these rifles. Rounds for this rifle don't cost anywhere near 5-10 bucks to feed them...another gross exaggeration...unless you are shooting match ammo...and even then its not 10 bucks a round.

I know many who still shoot their 50's from the two buys we did. And none of them have had an issue...imagine that.

Maybe I should offer up an ammo group buy for those of you who are paying more than 3 bucks a round.

Gotta love the fact many more will be putting rounds through these rifles. The design might not be to your liking, but many others have decided it is to theirs. Price points and design...hits on both.

I’ll say it again…to me, it’s just an oversized zip gun.
